Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water dispenser for supplying cold or hot water suitable for drinking.

[0002]

2. Description of the Related Art Since tap water is sterilized with chlorine or the like, it can be safely consumed. However, tap water has
Tap water is not delicious because it contains chlorine, has a musty odor, and contains rust generated in water pipes. Therefore, there is a structure in which tap water is passed through a water purifying device, for example, a water purifier to remove (that is, purify) the above-mentioned various kinds of inclusions and obtain delicious water. The water purifier has a filter that removes various kinds of inclusions. Further, there is a water dispenser configured to store such purified water in a tank and to cool the tank by an evaporator, which is a cooling means, so that cold water can be supplied from the tank when necessary. Also,
There is a water dispenser configured to heat the tank by a heater so that hot water can be supplied from the tank when necessary.

[0003]

However, in the water supply device of the above-mentioned conventional structure, since purified water having no bacteriostatic action is stored in the tank for a long time, various bacteria may propagate in the water. In particular, various bacteria are often propagated in the water accumulated in the pipe for supplying water from the tank to the outside, and it is necessary to discard the water in which such bacteria are propagated. For this reason,
When using the water dispenser, one had to first drain water.

On the other hand, the applicant of the present invention has invented a water supply device which does not require waste water and applied for it earlier (Japanese Patent Application No. 7-265473). The water supply device is configured to cool (or heat) tap water, purify the cold water (or hot water) through a water purifier, and supply the purified water. In the case of this configuration, since the water is purified by the water purifier at the final stage of water supply from the water dispenser, the water to be supplied does not contain any germs, and it is not necessary to discard the water.

However, in the water supply device having the above structure, the cold water may be warmed when passing the cold water through the water purifier. In this case, if you pass a certain amount of cold water through the water purifier,
Since the water purifier is cooled, cold water is discharged from the water purifier thereafter. Therefore, when the user wants cold water, it is necessary to discard the water until the water purifier is cooled, and as a result, several hundred cc of the discarded water must be disposed. Further, such waste water was also required when hot water was supplied.

Therefore, an object of the present invention is to provide a water supply device that can supply cold (or hot) purified water from the beginning and that does not require waste water as much as possible.

[0007]

The water supply device of the present invention comprises a tank for storing water, a water purification means for purifying the water sent from the inside of the tank to produce purified water, and the tank or the inside of the tank. It is characterized in that it comprises a cooling means for cooling water, and an insulating box for accommodating the tank, the cooling means and the water purification means.

According to the above construction, since the inside of the heat insulation box is cooled by the cooling means, the water purification means is also cooled. Therefore, when using the water supply device, cold water comes out from the water purification means from the beginning. This allows
Almost no waste water is required.

Further, in the case of the above construction, it is also possible to stop the provision of the heat insulating box and to cool the tank and the water purification means simultaneously from the outside by the cooling means. Further, another water supply device of the present invention is, a cold storage tank for storing the cold storage material cooled by the cooling means, a water pipe provided in the cold storage tank for circulating tap water, and provided in the cold storage tank, It is preferable that the water purification apparatus is provided with a water purification means for purifying the water sent through the water pipe and discharging the purified water.

In this case, it is more preferable that the water purifying means is housed in the filter tank provided outside the cold storage tank and that the cold storage material in the cold storage tank is circulated and supplied into the filter tank. . Further, in each of the above configurations, instead of the cooling means for cooling the tank or the water in the tank, or the cooling means for cooling the cold storage material, a heating means for heating the water in the tank or the tank, or a heat storage material It is also a preferable configuration to provide a heating means for controlling the hot water so that hot water is discharged from the water purification means.
